See your eye doctor: For your symptoms of floaters you should see your eye doctor right away to see if it's the sign of a serious problem. As for your other symptoms, they should warrant some further testing.
I believe that it is correct to say that RNA is not replicated, but reproduced. DNA, what I know currently, is the only one that replicates itself.   Plus, to my knowledge, you don't need to copy a RNA strand.
Transcription and DNA replication both involve making copies of the DNA in a cell. Transcription copies the DNA into RNA, while replication makes another copy of DNA.imilarities. Both DNA replication and transcription involve binding complementary nucleic acids to DNA, yielding a new strand of either DNA or RNA. Both processes can lead to errors if an incorrect nucleotide is incorporated.
